1 the machine andwhich is mounted upon trac- The object of my invention is to produce a simple inexpensive machine that when in op-; eration requires but very little attention and tion-wheels 2 in order that the machine may be readily moved from one place to another. Rigidly fixed to the center of the base 1 and projecting upwardly'therefrom is a post 2..

- 3indicates a sleeve that is rigidly positioned on the post 2 a short distance above the base 1, said sleeve supporting a rotating table 4. The outer edge of this table 4L bears upon a ring 5, that is supported by standards 7 Rigidly secured to the under side of the table 4 is a circular rack 6, the teeth of which are beveled.

Rotatably arranged in suitable bearings 8 immediately to the rear of the post 2 is a horizontal shaft 9, carrying a beveled gearwheel 10, that meshes with the teeth of the circular rack 6. On the outer-end ofthe shaft 9 is a disk 11, provided in its outer face with a series of outwardly-projecting pins 12, there being the same number of these pins as there are blow and blank molds carried by the table 4., as hereinafter described.

Formed in the outer portion of the table 4 is a series of circular apertures 13 equidistant apart and adapted to receive the bases of the blow and blank molds of the press. These blow and blank molds are arranged alternately. Formed in the top surface of the table 4 immediately adjacent these openings 13 are notches 14. Adapted to 'engagein these notches are the inner portions of a lockingfinger 15, which is divided at its center by a.

knife-blade hinge l6, and being pivotally arranged in the upper end of a standard 17 that extends upwardly from the base 1. (See Figs. 9 and 10.) Arranged immediately above the table 4 and rigidly secured to the post 2 is a disk 18, in the top of which is formed a camgroove 19, a portion 20 of which extends closer to the center of the disk than the remainder of said groove.

The blowmolds, which will now be described, comprise mating portions 21, hinged together by pins 22 and each half provided with a pair of outwardly-projecting ears 23. The mating parts 21 of each mold are normally positioned on a base-plate 24, which base-plate is provided with a depending portion 25, that passes through its corresponding opening 13 in the table 4. The pins 22, that hinge the mating parts of the mold together, have their lower ends seated in the table 4, and in their upper ends are formed pin-holes 27. The top surface of each blow-mold when together is provided with an annular groove 28, and the opening into said mold at the upper end is slightly depressed, as indicated by 29. (See Fig. 11.)

Rigidly secured to the post 2 above the disk 18 is a collar 30, on which is rotatably arranged a ring 31, from which projects outwardly a series of rods 32, there being the same number of these rods as there are blowmolds, and the outer ends of said rods'slide through suitably-formed apertures in the upper ends of blocks 33, that are arranged to travel on the outer edge of the disk 18. Each block 33 is provided with a downwardly-projecting pin 34, that enters the cam-groove 19 in the disk 18, and each pin is provided with an antifriction-roller 35, that rides in said groove. (See Fig. 3.) Each block 33 is provided on its sides with laterally-projecting cars 36, and pivotally secured between each pair of said ears are the ends of rods 37. Pivotally secured between each pair of ears 23 on the sectionsof the blow-mold are the ends of rods 38, and each corresponding pair of rods 37 and 38 is joined by turnbuckles 39. (See Figs. 2 and 3.)

The blank-molds made use of in my improved machine comprise cylindrical blocks 40, each provided with a centrally-arranged tapering chamber 41, said blank-molds being arranged alternately between the blow-molds and'provided on their under sides with circular projections 42, that are seated in the corresponding apertures 13 in the table 4. Extend ing from the chamber 41 in each blank-mold, through the bottom thereof, is an aperture 43, in which is loosely arranged a pin 44, having its upper end formed into a taper valve 45, that seats in the lower end of the chamber 41. In the top of each blank-mold is formed an annular groove 46, corresponding in size to the annular groove 28 in the top of the blowmold. Rigidly fixed upon the post 2 a distance above the collar 30 is a collar 47, on which is seated a ring 48, provided with an outwardly-projecting arm 49, which carries the blowing-valve now to be described. This valve comprises a vertically-arranged cylindrical casing 50, that occupies a position immediately over the path of travel of the molds carried by the table 4. The cylindrical casing 50 is provided with an annular chamber 51, into which leads an aperture 52, and said aperture communicating with a hollow stem 53, that is seated in the wall of the casing 50. To this stem 53 is fixed the pipe 54, that conveys the compressed air or other blowing medium from its source of supply. Arranged to slide vertically through the casing 50 is a rod 55, the lower portion 56 of which is hollow, and rigidly secured to the lower end of said hollow portion is a plate 57, there being an apertured plug 58 seated in the lower end of said hollow portion 56. An expansive coilspring 59 is located upon the portion 56 of the rod 55 and interposed between the lowerend of the casing 50 and the plate 57. Formed through the wall of the upper part of the hollow portion 56 of the rod 55 is an aperture 60, which when the rod 55 is in its lowermost position establishes communication between the annular chamber 51 and the interior oi the hollow part 56 of the rod 55. Located upon the upper portion of the rod 55 is a roller 61, which is engaged by the bifurcated end 62 of the horizontal arm of a bell-crank 63, that is pivoted at 64 to a portion of the arm 49. The lower end of the vertical arm of this bell-crank 63 is provided with an antifriction-roller 65.

Extending upwardly from the ring 31 is a series of rods 66, upon which is mounted a disk 67, provided with four outwardly-projecting lugs or earns 68, the same being arranged at equal distances apart. The outer edges of these cams or lugs and disks 67 ride directly against the antifriction roller 65. (See Figs. 1 and 11.)

Rigidly secured to the upper end of the post 2 and projecting laterally therefrom is a bracket 69, to the outer end of which is rigidly secured a cylinder 70. Arranged to slide vertically through this cylinder 70 is a tubular piston-rod 71, on which is mounted a piston 72 within the cylinder 70, and through which tubular piston rod passes a screwthreaded rod 73. Arranged to slide through vertical bearings 74 on opposite sides of the cylinder 70 is a pair of rods 75. Adjustably positioned on the upper portion of the screwthreaded rod 73 and held in position by means of nuts 76 is a plate 77, the ends of which receive the upper ends of the rods 75, there hcing collars 78 located upon said rods immediately beneath the ends of said plate 77.

To the upper end of the rod 73 is secured a socket 79, which carries a horizontally-arranged pin 80, that projects through a slot 81, formed in the end of a lever 82, which is fulcrumed to the upper end of a bracket 83, that extends upwardly from the top of'the post 2*f .The outer end of this lever 82 terminates at a point immediately over the'disk 11, and loosely connected to the outer end of said lever is the upper end of a rod 84., that passes through a vertical guide 85 on the end of a bracket 86, secured to the upper end of the post 2*, andto the lower end of saidrod 84 is secured one .end of'a turnbuckle 87. Into the lower end of said turnbuckle is secured the upper end ofa rod 88,. thelower end of which is linked at 89 to a rod 90, that extends downwardly to a point immediately in front of the disk 11.

(See Figs. 1 and 8.) The lower end of this? rod 90 is bifurcated and adapted to engage over the pins 12,-carried by the disk 11, one

arm 91 of said bifurcated end being much longer than the opposite arm. This rod 90 carries an adjustable block'92, that is adapted to engage against the outer end of the locking-finger 15 when said rod 90 moves downf wardly.

Formed in the wall of the cylinder 70 is a' vertically-extending port or passage 93, the ends of which terminate at the upper andlower ends of the chamber within the cylinder 70. At the center of this port or passageway is formed a valve-casing 94:, which is provided with an ordinary stuffing-box 95 and in which is rotatably arranged a tapered valve 96, in the opposite sides of which are formed grooves 97. Leading into the valve-chamber v9 1'at right angles to the port or passage-way 93 is the inlet-port 98, and formed in the valve-casing 94 directly opposite this inletvport is theexhaust-port 99.

The grooves 97 are so arranged that when steam or compressed air is allowed to enter the cylinder above the piston the steam or compressed air that is below the piston will exhaust out through the lower portion of the port or passage-way 93 and the exhaust-port 99, or vice versa.-

The valve 96 is provided with a valve-stem 100, to the outer end of which is secured a le ver'101, and to the outer end of said lever is pivotally secured the upper end of a rod 102,

that extends downwardly to the base 1 and is there pivotally secured to a foot-lever 103.

A retractile coil-spring 10 1 is secured to .the

lever 101 and to a pin 105, projecting outwardly 'from the cylinder 70. This spring normally holds the valve 96 so' that the pressure medium is beneath the piston 72 and holds the same in the upper end of the cylinl der 70, as seen in Fig. 6. The lower end of the plate 106 is adjustably seated a plate 110, through the outer portions of which pass rods 7 111, the lower ends of which carry .a ring 112, through which the plunger 109' passes, and expansive coil-springs 113 are arranged upon these rods 111 and interposed between the plates 110'and 112. .Rigidly secured to the lower ends of the. rods below the plate 106 is a ring 114:, provided on its edges with the upwardly-projecting flanges 115. Formed through thisring 114:, onopposite sides there- 7 5 of, are the short horizontal slots 116. Arranged for slight rotary movement upon the ring .11 1 between the flanges 115 is a ring 117, the same being provided with an operating-handle 118, that projects through an opening 119, formed in the outer one of the flanges 115. Formed in the opposite sides of this ring 117 and immediately over the slots 116 are the diagonally-arranged slots 120. The upper ends of pins 121 pass through the corresponding slots 116 and 120, the lower ends of said pins being rigidly secured to horizontally-arranged fingers 122, that pass through depending portions of the ring117 beneath the rods 75, and the inner ends of said fingers 122 are provided with the horizontally-arranged lugs 123. The lip-ring,'whichcomprises apair of semicircular mating sections 12 1, hinged together by a pin 125, is provided with operating-handles 126, and said lip-ring is provided in its outer face withan annular groove 127, inwhich, is adapted to engage the lugs123. The underside of said lip-ring is provided with an annular flange 128 and is so formed as to fit snugly upon the top surface of either the blank-mold or blow-mold, and the inner face of said lip-ring is provided with an inwardly-projecting flange 129.

The operator stands immediately in front of the machine or immediately adjacent the 5 blank-mold (indicated by A, Fig. 2) and operates the foot-lever 103, which controls the valve 96, that allows the pressure medium to pass alternately above and below the piston v 72 in the cylinder 70. The'table 4 rotates in- 9 0 termittently, as will be hereinafter described,

and a-proper quantity of molten glass is de posited in each blank-moldas it comes around to the point marked .B, Fig. 2. After two more intermittent. movements of the table this I I 5 particular blank-mold containing the proper quantity of glass is brought to the position A and immediately beneath the plunger 109. I The operator now manipulates the foot-lever 103 so as to turn the valve 96 and allows the I20 pressure medium to pass into the upper end of the cylinder 70, thus forcing the piston 7 2, piston-rod 71, and rod 73, and various parts carried thereby downwardly. Previous .to 7 this downward movement of the plungerand 5 various parts carried by the pistonand piss ton-rod the operator places a lip-ring 124E upon the top ofthe blank-mold, said lip-ring being closed and with its depending flange 128 occupying the annular groove 46 in the top of the blank-mold. The operating-handle 118 .had previously been moved so as to shift the as it moves downwardly to its limit of movement forms the molten glass in the blankmold 40 and forces a portion thereof upwardly around the inner edge of the lip-ring 124 and around the flange 129 thereof. The operator now by means of the handle 118 shifts the ring 117 so as to bring the pins 121 to the inner ends of the slots 116, and this movement causes the lugs 123 to engage in the annular groove 127 in the outer edge of the lip-ring. The operator now removes his foot from the foot-lever, and the retractile coil-spring 104 draws the lever 101, rod 102,

and lever 103 upwardly, thus shifting the valve 96 into a position whereby the pressure medium is transferred from the chamber above the piston 72 to the chamber beneath, and correspondingly the piston, piston-rod 71, rods 75, and parts carried thereby will be elevated, and in so doing the lugs 123, engaging the lip-ring 124, will carry said lipring upwardly, which lip-ring now carries the molten-glass blank. As the various parts move upwardly the forward end of the lever 82 will be elevated and the rear end thereof depressed, and as the rods 84, 88, and 90 move downwardly the bifurcated lower end of :the rod 90 will engage one of the pins 12 of the disk 11 and partially rotate said disk, and as a result the shaft 9 and beveled gearwheel 10 will be likewise partially rotated. As said rod 90 moves downwardly the block 92 will engage the outer end of the lockingfinger 15 and raisethe inner end thereof out of the notch 14, in which it was seated, thus allowing the table 4 to be partially rotated as the partial rotary motion of the beveled gearwheel 10 is imparted to the circular rack 6. This partial rotation of the table brings one of the molds to the point A directly in front of the operator, and he again operates the foot-lever 103, so as to shift the valve 96 and allow the pressure medium to pass into the cylinder above the piston and force the parts downwardly,'as hereinbefore described. This movement locates the glass blank in the blowmold, and after it has been accomplished the operators foot is removed from the treadle and the reverse movement again takes place, as hereinbefore described, and the table is shifted its proper distance, so as to bring the rectly upon the lip-ring 124.

blow-mold containing the glass blank into the position 0, Fig. 2, or immediately beneath the blow-valve, and when so positioned a blank-mold filled with molten glass is at the pointA immediately beneath the plunger. As the table 4 rotates and the molds move around therewith the blocks 33 move around on the disk 18, and the ring 31 is likewise moved. The plate 67, carrying the lugs 68, being connected with said ring 31, moves therewith, and the lugs are intermittently and successively brought around into engagement with the roller 65, and as a result thereof the bellcrank 63 is operated and the rod 55 and plate 57 are elevated, as seen in Fig. 11. The tendency of the coil-spring 59 is to force the plate 58 downwardly, as shown by dotted lines in Fig. 11, and consequently the roller is always in engagement with the edges of the lugs 68. The disk 67, carrying these lugs, is so arranged that the roller 65 is at a point between two of the lugs 68, and when in this position the rod 55 and plate 57 are at their lowermost limit of movement, said plate 57 resting di- This action brings the port 60 into communication with the annular space 51 in the valve-cylinder 50, and the compressed air used for blowing is now free to pass from the tube 54 downwardly through the hollow portion 56 of the rod 55 and into the glass blank within the blow-mold, and said glass blank is blown into proper shape. The next intermittent movement of the table 4 brings one of the lugs against the roller 65, and the various parts just mentioned are elevated, and the blowingair to the blow-mold is cut off. The table 4 is intermittently moved in the manner hereinbefore described until the blow-mold containing the bottle or jar properly blown reaches the rear side of the machine or at a point directly opposite the operator, and when in this position the antifriction-roller 35 travels into the portion 20 of the groove 19, thus drawing the block 33 inwardly toward the post 2" and opening the mold, as shown by dotted lines in Fig. 2. The blown bottle or jar and the lip-ring, which latter opened with the blow-mold, are now removed, and the operation is complete.

A glass-blowing machine of my improved construction is comparatively simple, is practically automatic, therefore requiring very little attention, and a large number of uniformly-blown jars or bottles can be turned out in a comparatively short space of time.
